The British Rail Class 322 electric multiple units were built by British Rail Engineering Limited in 1990 for the dedicated Stansted Express service from London Liverpool Street to Stansted Airport. After becoming surplus to requirements on this route, the fleet saw short periods of use on various different routes around the country. The fleet is operated by Northern and can be seen working services around the Leeds area.
In 1987 British Rail (BR) was extending electrification north from London Liverpool Street towards Cambridge. Included in this plan was the construction of new branch line, diverging from the main line at Stansted Mountfitchet, to serve the newly built Stansted Airport, which opened in 1991. BR decided to build a dedicated fleet of units to work a new service called Stansted Express.
To reduce costs the Class 322 units were built to the same basic design as the successful Class 321 units, which were still under construction for services on the Great Eastern Main Line (GEML) and West Coast Main Line (WCML). Although the Stansted route fell under the jurisdiction of Network SouthEast (NSE), the units were delivered into service in a special white livery with a broad green band, instead of the more usual NSE blue/red/white livery.
The units are fitted with Tightlock couplers. This allows them to work in multiple with Class 313, Class 314, Class 317, Class 318, Class 320 and Class 321 units, as well as other units of the same class.
Five 4-car units were built, numbered 322481–485. Each unit consisted of two outer driving trailers, an intermediate trailer and an intermediate motor coach. The technical description of the formation of each unit is DTCO+TSO+MSO+DTSO. Individual vehicles are numbered as follows:
- 78163–78167 – DTCO
- 72023–72027 – TSO
- 63137–63141 – MSO
- 77985–77989 – DTSO
The units were the last of a long line of BR multiple units to be based on the Mark 3 bodyshell design.
The Class 322s operate services with Northern and are used to provide services between Leeds and Doncaster as well as the Leeds-Skipton-Bradford-Ilkley "Triangle".
Small technical changes have been made in order for them to be used in the area. These include forward-facing CCTV and saloon CCTV installation and electronic LED destination displays and automatic GPS based announcing system (as per the Class 321/9 units).
In early 2016 it was confirmed that Spanish rolling stock manufacturer CAF are to construct the new electric Class 331 trains which are planned to operate in West Yorkshire to replace Class 321 and Class 322 trains and work alongside the current fleet of Class 333 units.
West Anglia Great Northern
Following privatisation, the fleet passed into control of the West Anglia Great Northern (WAGN) franchise. At the same time, services were rebranded as the Stansted Skytrain.
Units continued to be used on these services until 1997, when they became common-user with the rest of the WAGN fleet. After this, it was common for units to turn up on London King's Cross to Peterborough services. Four of the five units were subsequently hired to North Western Trains.
However, on return to WAGN, they did not have any specific duties to work, as dedicated rebuilt Class 317/7 units were introduced to the Stansted Airport services in 2000. The Class 322 fleet therefore remained non-standard in WAGN's fleet, so in 2001 all five units were hired to ScotRail, who operated similar Class 320 units. The class was transferred north to Scotland in two batches under their own power, routed via the West Coast Main Line.
North Western Trains
These services did not last long, and by 1999 the units had returned to WAGN.
From 2001 the units – having been made redundant on WAGN services – were used by First ScotRail, operating on the North Berwick Branch Line, between Glasgow Central/Edinburgh Waverley and North Berwick. They were transferred north to Scotland and were put to work allowing the elderly incumbent Class 305 slam-door units to be withdrawn. One morning and one evening peak service were provided to Glasgow Central via the relatively quiet Edinburgh–Carstairs branch of the WCML to allow the units to receive maintenance at Glasgow Shields depot as First ScotRail's facilities in Edinburgh (at Haymarket and Slateford depots) are for diesel traction only.
The units continued to be used on these services until mid-2004, when the hire period ended. They were transferred south in two batches, and were replaced on the North Berwick branch by EWS Class 90 electric locomotives hauling former Virgin Trains Mk.3 coaching stock. To enable trains to reverse the locomotive operated in push-pull mode with a Driving Van Trailer.
In mid- to late-2005 the units were transferred back to Scotland for refurbishment prior to reintroduction on the North Berwick line, which was expected to be their permanent use. In Spring 2006, the first unit to be refurbished and repainted in the First ScotRail livery was unveiled. The units were refurbished at Hunslet-Barclay, Kilmarnock, between 16 July 2005 and 9 February 2007. 322481 was the first one repainted, and it took the name that 322485 carried when the class previously operated the route. The remaining units were refurbished and repainted into First ScotRail livery. However, one unit, no. 322481, was named North Berwick Flyer, 1850–2000.
In 2010, with the introduction of Class 380 "Desiro", the North Berwick Line saw a fleet replacement which began operations in June 2011. The last service operated by a Scotrail Class 322 was the 0756 North Berwick–Glasgow Central service on 2 August 2011. All five units have since been transferred to Northern Rail.
